==NAT 设置==

===修改 /usr/local/freeswitch/conf/var===
 注释掉：
 <X-PRE-PROCESS cmd="set" data="external_sip_ip=stun:stun.freeswitch.org"/> 
 换成
 <X-PRE-PROCESS cmd="set" data="external_sip_ip=*.*.*.*"/>
 <X-PRE-PROCESS cmd="set" data="external_rtp_ip=stun:stun.freeswitch.org"/>
 换成
 <X-PRE-PROCESS cmd="set" data="external_rtp_ip=xxx.xxx.xxx.xxx"/>

===修改/usr/local/freeswitch/conf/sip_profiles/external.xml===
  修改为
  <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
  <param name="ext-sip-ip" value="$${external_sip_ip}"/>

===修改修改/usr/local/freeswitch/conf/sip_profiles/internal.xml===
 <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
 <param name="ext-sip-ip" value="$${external_sip_ip}"/>

===查看nat 设置===

radius 模块相关配置

打开mod_radius_cdr
    <!-- Event Handlers -->
    <load module="mod_cdr_csv"/>
    <!-- <load module="mod_cdr_sqlite"/> -->
    <!-- <load module="mod_event_multicast"/> -->

    <!-- <load module="mod_snmp"/> -->
    <load module="mod_radius_cdr"/>
   重启freeswitch 生效
   fs_cli -x 'fsctl shutdown restart'

===mod_radius_cdr.conf.xml===
  如果在/usr/local/freeswitch/conf/autoload_configs
  /usr/local/freeswitch/mod/上要加mod_radius_cdr.la ；mod_radius_cdr.so 的模块，然后重启freeswitch。

==中文语音包==

===上传中文包到 /usr/local/freeswitch/sounds/===
:下载文件： [[文件:Freeswitch-sounds-zh-cn-link-8000-1.0.0.tar.gz]] 上传
 cd /usr/local/freeswitch/sounds
tar -zxvf freeswitch-sounds-zh-cn-link-8000-1.0.0.tar.gz
===增加中文定义===
 cd /usr/local/freeswitch/conf/lang
 cp -a en zh
 cd zh
 mv en.xml cn.xml

===编辑cn.xml===
:将cn.xml第2行换成
 <language name="zh" say-module="zh" sound-prefix="$${sounds_dir}/zh/cn/link" tts-engine="cepstral" tts-voice="callie">
===增加对中文的加载===
编辑/usr/local/freeswitch/conf/freeswitch.xml，找到<section name="languages" description="Language Management">段，加入
 <X-PRE-PROCESS cmd="include" data="lang/zh/*.xml"/>
===增加中文say模块的加载===
:编辑/usr/local/freeswitch/conf/autoload_configs/modules.conf.xml
 去除<load module="mod_say_zh"/>的注释
===设置中文为默认语言===
:编辑/usr/local/freeswitch/conf/vars.xml，加入以下几行
  <X-PRE-PROCESS cmd="set" data="default_language=zh"/>
  <X-PRE-PROCESS cmd="set" data="default_dialect=cn"/>
  <X-PRE-PROCESS cmd="set" data="default_voice=link"/>
===重新加载xml===
:在fs_cli
 reloadxml

==freeswitch lua 通话超时自动挂断==

{execute_on_answer='sched_hangup +"..calltime.."'} calltime为允许通话的时间,单位为秒

freeswitch.Session("{origination_uuid= "..matchcode.."}{execute_on_answer='sched_hangup +"..calltime.."'}

==freeswitch调节通话声音大小==
